				"Variable Fonts" supported in epub?
			 
			
			
			Are variable fonts supported in epub yet? Anyone have experience with this? A google search didn't really give me any answers. I'm guessing it's just too new to be supported. 
		
	
		
		
		
		
		
		
		
		
		
		
	
	For those who don't know about variable fonts, here is a fairly exhaustive article https://medium.com/variable-fonts/ht...ts-12ba6cd2369  |

			It sounds like this is more an issue for ePub reading software rather than the ePub spec itself.

			The EPUB 3 Core Media Types specification calls out the following specification for OpenType: 
		
	
		
		
		
		
		
		
		
		
		
		
	
	ISO/IEC 14496-22:2009 - Information technology -- Coding of audio-visual objects -- Part 22: Open Font Format. This is the ISO's version of the OpenType specification from 2009. It significantly pre-dates font variations that were introduced in Microsoft's OpenType version 1.8 in 2016. I would say that embedding a font in an EPUB that does not comply with the 2009 specification would result in a non-compliant EPUB. It might be handled by some e-readers, but certainly not by all.  |
